What factors affect stomatal conductance in high school biology?

Stomatal conductance will affect photosynthesis, respiration and transpiration.

Stomatal conductance indicates the degree of stomatal opening and affects photosynthesis, respiration and transpiration (Gs for short). Its unit is mmol m-2s-1,and it can also be expressed by stomatal resistance. Are quantities that describe the stomatal opening.

Stomata are the main channels for gas exchange between plant leaves and the outside world. Gases diffused through pores are O2, CO2 and water vapor. Plants photosynthesize under light and absorb CO2 through stomata, so stomata must be opened, but transpiration inevitably occurs when stomata are opened. Stomata can adjust their opening according to the change of environmental conditions, so that plants can get the most CO2 with less water loss.
